| Research Abstract |
For spaces with curvature bounded above, especially CAT(k) spaces, I have aimed to unite the metric geometry with the geometric topology. As joint works with Lytchak, I have mainly tried to study the wall type singularity of CAT(k) spaces, the polyhedral local topological regularity of CAT(k) spaces, and the asymptotic topological regularity of CAT(0) spaces, and obtain several versatile results.
